Since 1947, Norris & Son, Inc. has operated
as a full services Refractory Contractor
with offices located in Chattanooga, Tennessee.

N&SI has built upon our experience, the installation and maintenance of not only various types of boilers, but also, incinerators, cupolas and ovens of all sizes, all types of kilns, ducts, smelters, dryers, ladles, and various processing tanks as well. We have worked in more than 30 states and overseas. The U.S. Treasury Department hired N&SI to reconstruct a highly classified incinerator for currency and we have worked on ocean going vessels sailing to South America and Panama.

NS&I was built on a strong family reputation with the idea of giving the customer: Quality; Commitment; and a Good Value for the Dollar. With the third generation running the company since 1985, the years have not changed those strong standards of business promises. Our stability and longevity stand firm and we truly place our reputation behind the work we perform and the products we sell 100%.
